Abstract

Web Content Accessibility Guidelines 2.0 (WCAG 2.0) covers a wide range of issues and recommendations for making Web content more accessible. This document contains principles, guidelines, success criteria, benefits, and examples that define and explain the requirements for making Web-based information and applications accessible. "Accessible" means usable to a wide range of people with disabilities, including blindness and low vision, deafness and hearing loss, learning difficulties, cognitive limitations, limited movement, speech difficulties, and others. Following these guidelines will also make your Web content more accessible to the vast majority of users, including older users. It will also enable people to access Web content using many different devices - including a wide variety of assistive technologies.

The Web Content Accessibility Guidelines Working Group (WCAG WG) encourages feedback about this Working Draft. Since the 30 June 2005 WCAG 2.0 Working Draft, the WCAG WG has focused on addressing comments received on previous drafts and introducing a new format to make it easier to access support and explanatory information for each success criterion. This draft represents a significant reorganization of the WCAG document set (guidelines and support documents) and includes changes to success criteria as well as rationale and a listing of techniques deemed as sufficient for each success criterion. Does this new organization work for you? Does the new support information provide the information you need most? Are the success criteria at the right level? Are the success criteria wording accurate and understandable? Please refer to "Issue Tracking for WCAG 2.0 Working Draft" for a list of open issues related to this Working Draft. The "History of Changes to WCAG 2.0 Working Drafts" is also available.
